I'm using the handsontable library for creating neat tables.
I literally copied the tutorial but the console (web developer console) gives me the following error:
Uncaught TypeError: Cannot read property 'insertBefore' of undefined
handsontable.full.js:4471
I link both the .css and the .js file correctly in the <head> tags.
My javascript looks like this:
var data = [
["", "Ford", "Volvo", "Toyota", "Honda"],
["2016", 10, 11, 12, 13],
["2017", 20, 11, 14, 13],
["2018", 30, 15, 12, 13]
];
var container = document.getElementById('temp');
var hot = new Handsontable(container, {
data: data,
rowHeaders: true,
colHeaders: true,
dropdownMenu: true
});
Html:
<div id="temp"></div>
Line 4471 in handsontable.full.js is
rootElement.insertBefore(this.container, rootElement.firstChild);
The table isn't displayed, the error in the console is all I've got.
It looks like that your
document.getElementById('temp');
return undefined.
Make sure that the container element is still there when Handsontable is constructing.
Your rootElement reference is undefined. Please check where is this variable defined and to what it is assigned.
